本願は、２０１２年１１月３０日に、日本に出願された特願２０１２－２６２２４６号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to a bag body with a fitting tool.
This application claims priority based on Japanese Patent Application No. 2012-262246 filed in Japan on November 30, 2012, the contents of which are incorporated herein by reference.
食品、薬品等の様々な分野において、袋本体の開口部の近傍の内面に、開口部を開閉自在に封じる嵌合具が取り付けられた嵌合具付き袋体が広く用いられている。嵌合具としては、例えば、一対の帯状の基材のそれぞれの対向面に、開口部の開閉方向に延びる突出部である雄側嵌合部及びこの雄側嵌合部に着脱自在に嵌合する雌側嵌合部が、それら基材の長手方向に沿ってそれぞれ設けられた嵌合具が知られている（特許文献１）。嵌合具付き袋体においては、袋体の開口部の近傍の内面に上述の開口部の縁に沿って嵌合具が取り付けられ、上記の嵌合具の雄側嵌合部と雌側嵌合部とを着脱することで、袋体の開口部を開閉自在に封じることができる。
In various fields such as food and medicine, a bag body with a fitting tool in which a fitting tool for opening and closing the opening portion is attached to the inner surface in the vicinity of the opening portion of the bag body is widely used. As a fitting tool, for example, a male-side fitting portion that is a projecting portion extending in the opening / closing direction of the opening and a male-side fitting portion are detachably fitted to the opposing surfaces of a pair of belt-like base materials. There has been known a fitting in which female side fitting portions are provided along the longitudinal direction of the base materials (Patent Document 1). In a bag body with a fitting tool, a fitting tool is attached to the inner surface in the vicinity of the opening of the bag body along the edge of the opening, and the male fitting portion and the female fitting of the fitting tool are attached. By attaching and detaching the joint portion, the opening of the bag body can be opened and closed freely.
一方、食品、薬品等の分野においては、保存時や使用時等における内容物の温度を制御する必要がある場合が多い。例えば、保存時においては冷蔵また冷凍保存が要求され、使用時には常温に戻して使用されるもの等が挙げられる。
このような場合、保存時間や、室温等で放置して常温に戻すための時間が長ければ、嵌合具付き袋体に収容した内容物の温度を判断することは比較的容易である。しかし、これらの時間が充分に長くない場合は、内容物の温度を判断することが難しい。また、嵌合具付き袋体の袋本体の材質によっても袋体内の温度変化の速度が変わることから、内容物の温度を直ちに判断することは難しい。 On the other hand, in the field of food, medicine, etc., it is often necessary to control the temperature of contents during storage or use. For example, refrigerated or frozen storage is required at the time of storage, and those that are returned to room temperature when used are used.
In such a case, it is relatively easy to determine the temperature of the contents accommodated in the bag with fittings if the storage time or the time for leaving it at room temperature to return to room temperature is long. However, if these times are not long enough, it is difficult to determine the temperature of the contents. In addition, since the speed of temperature change in the bag body varies depending on the material of the bag body of the bag body with a fitting, it is difficult to immediately determine the temperature of the contents.
